Fungi and plants used to be considered part of the same group of living organisms, but not anymore. Plants are different from fungi because plants make their own food via photosynthesis and fungi does not. Fungi instead is a decomposer and gets nutrients from other sources. Also, fungi does not have chlorophyll which plants have and is how they get their green color. Another difference is that plants reproduce using seeds and fungi reproduce using spores. The biggest difference is their role in the ecosystem. Plants are considered producers and provide nutrients to other organisms and fungi are decomposers which break down other organisms.
They are similar in that they are stationary organisms and reproduce via sexual and asexual means.
